The taxonomic status of six strains Acinetobacter obtained from meat samples, collected supermarkets in Porto, Portugal, was investigated using polyphasic analysis. Partial rpoB sequence similarities lower than 95 % to other species with validly published names led the hypothesis that these represented novel species. This confirmed based on comparative multilocus analysis, which included gyrB , recA and 16S rRNA genes, revealing two coherent lineages were distinct each all known portensis sp. nov. (comprising four strains) guerrae are proposed for groups by low (below %) whole-genome average nucleotide identity values 70 digital DNA–DNA hybridization between sequences type representatives Phylogenomic treeing core genome analysis supported results. coherence new lineage matrix-assisted laser desorption/ionization time-of-flight mass spectrometry differentiation at protein level, cellular fatty acid profiles, unique differential combinations metabolic physiological properties shared strain A. is AC 877 T (=CCUG 68672 =CCM 8789 ) 1271 68674 8791 ).
